To evaluate the health benefits brought about by air environmental treatment and determine the main drivers of health risk, we calculated the health and economic benefits attributed to PM
control in Eastern and Central China from 2013 to 2017 by combining PM
concentrations with a human activity enhanced exposure-response model. The relative contributions of changes in four factors related to the PM
health burden were also quantified, namely total population, population aging, baseline mortality rates, and ambient exposure. The results show that the population weighted PM
concentration decreased by 28.73% and the proportion of the population exposed to annual PM
concentrations lower than or equal to 35 μg·m
increased from 11.23% to 27.91% across the study area during this period. Avoided deaths were decreased to 14.43%, which equates to avoided economic losses of approximately 559 billion RMB. If PM
concentration meets the Chinese Ambient Air Quality Standard Grade Ⅱ (35 μg·m
) or Grade Ⅰ (15 μg·m
), or the Wo
